Degrees of freedom
A)in the context of the sample variance formula means that estimating the mean uses up some of the information in the data.
B)is something that certain undergraduate majors at your university/college other than economics seem to have an ? amount of.
C)are (n-2)when replacing the population mean by the sample mean.
D)ensure that $S _ { y } ^ { 2 } = \sigma _ { y } ^ { 2 }$

Question

Estimating the mean from the sample data uses up one degree of freedom, which is why the sample variance formula uses (n-1) instead of n.
